Definitely. Literally half of the features in the "What do we want?" section would get his replacement banned in the PRC, which is one of the few markets where WeChat is popular enough to even be something to replace.
And much more. Not going to through it all in detail, and there are probably many things I don’t know about WeChat since I’m not a heavy user living in mainland China.
The team definitely needs to get the experience of being behind the great firewall. Try using a VPN there to watch YouTube, try using a locally purchased cell phone without access to Google Play or the Apple app store. Try bashing PRC government policies in WeChat.
Only then will they see how tightly things are locked down. It's not like they're the only ones to have this idea, so why doesn't it exist? Oh, because it's really difficult and even dangerous with the current police state that controls the communications.
